Here we examine the pressure of ABPs in two dimensions in both closed boxes and systems with periodic boundary conditions and show that its nonmonotonic behavior with density is a general property of ABPs and is not the result of finite-size effects. We correlate the time evolution of the mean pressure towards its steady-state value with the kinetics of motility-induced phase separation. For parameter values corresponding to phase-separated steady states, we identify two dynamical regimes. The pressure grows monotonically in time during the initial regime of rapid cluster formation, overshooting its steady-state value and then quickly relaxing to it, and remains constant during the subsequent slower period of cluster coalescence and coarsening. The overshoot is a distinctive feature of active systems. 000152211 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/FIS2015-65078-C2-1-P 000152211 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000152211 590__ $$a2.284$$b2017 000152211 591__ $$aPHYSICS, MATHEMATICAL$$b7 / 55 = 0.127$$c2017$$dQ1$$eT1 000152211 591__ $$aPHYSICS, FLUIDS & PLASMAS$$b12 / 31 = 0.387$$c2017$$dQ2$$eT2 000152211 592__ $$a0.979$$b2017 000152211 593__ $$aCondensed Matter Physics$$c2017$$dQ1 000152211 593__ $$aStatistical and Nonlinear Physics$$c2017$$dQ1 000152211 593__ $$aStatistics and Probability$$c2017$$dQ2 000152211 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000152211 700__ $$0(orcid)0000-0001-7276-2942$$aYllanes, David 000152211 700__ $$aMarchetti, M.
